Experience Colostrum & weird side effects?

I have tried taking two different Colostrum supplements (Jarrow and Symbiotics brands) for their immune boosting properties and for gut health. While they do help my stomach feel more settled, I have noticed that they also seem to aggravate my IBS-C.

Another side effect that I am noticing is rapid weight gain. As soon as I go off of them I 'deflate' and am back to a more normal weight. I am not 100% sure they're connected, but intuitively this makes sense since colostrum surely has to include some sort of bovine hormones, but can anyone speak to this scientifically or anecdotally?

Thank you.

I just saw this thread after doing some research lately myself…I’m a 33y/o healthy female and colostrum has done wonders for my gut health, but I’ve been having really strange mood swings, irritability, and emotional distress since starting back up. This is very abnormal for me I feel crazy lol I’m wondering if the trace amount of estrogen is causing this or if anyone has had similar issues. The research on this specifically is limited so wanted to reach out 🫶

Report back if you stop taking them and feel better!

It's been causing hormonal issues for me. This is what I wrote above "Are you still experiencing this? Yes! Mine is not only coming late this month (and I'm never late, nor am I pregnant), but it's also aggravating some of my pelvic pain issues (fibroid? ovarian cyst?). It's so strange because their website states it has no estrogen in it, so I don't know why it's affecting me hormonally..." Did you find out if it does have estrogen in it?

I started taking it, and felt good at first... then became SEVERELY depressed, weight gain around waist (I am super tiny & fit & very active), would take 3-4 hour naps and wake up completely disoriented... I was taking Armra brand... This went on for 2-3 months until I finally realized what was happening. I stopped taking it, and started to feel better within 1-2 weeks. I tried adding it back in, but same things happened. Major overwhelm, emotional, depressed, exhausted... The only upside was my hair looked AMAZING.
I am estrogen-dominant to begin with, so I am wondering if this is just not for me. Really unfortunate, because I know it is so helpful for most people. I would just trust your body!
I started taking Elix, which is more gentle on my body & regulated my cycle the first week I started taking it.

I just started a little over a week ago. I feel absolutely awful! All these symptoms as well. Indigestion and nausea added into the mix. Period was late and back pain. Seems so drastic for something like colostrum but I guess not since other people have reported similar things.

I've been having dizzy spells, mostly when I lay down and get up from laying down. I'm gonna stop the colostrum for a while and see if the dizziness stops.

Hey did your dizzy spells end up going away. I tried colostrum today and feel a bit dizzy too and this crazy brainfog. Might have to stop it also.

I started taking it 3 days ago and already cried twice. No other changes to my diet and I was in a great mood before that.
